[NV/ENTERS Patented June 7, 1932 UNITED STATES hdiihdh'i FFLCE Q OSCAR L. SHERMAN, OF MEDFORD, AND ADELORD BOURGEOIS, OF SWAMPSCOTT, MASSA- CHUSETTS, ASSIGNORS TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY ROUNDING AND CHANNELING MACHINE Application filed April 26,

This invention relates to improvements in machines for operating upon the soles of shoes and is herein illustrated as embodied in rounding and channeling machine of the type disclosed in United States Letters Patent No. 600,883, granted March 22, 1898, upon application of I. 0. Meyer and Z. T. French. The invention is set forth hereinafter with particular reference to its application to the rounding and channeling of soles which have been applied to shoes in the process of repairing the shoes. The invention is not necessarily limited, however, in its application to repair work nor to machines for performing both rounding and channeling operations. Neither is the invention limited to embodiment in machines of the particular type disclosed in the patent referred to.

Machines of the type referred to are particularly designed for operation upon welt shoes and to this end each machine is provided with a fixed work support or socalled crease guide arranged to enter the welt crease of a shoe to assist in supporting the shoe in position to be operated upon. hen such a machine is used in connection with the repairing of welt shoes the machine is also provided with means in the nature of an edge gage or guide for engaging the previously trimmed edge of the welt of a shoe to guide the shoe as it is fed past the operating instrumentalities of the machine. Such machines, however, are not adapted to operate upon the soles of McKay-sewed shoes of the type having no welt or its equivalent to be engaged by the edge gage and, further, for the reason that, at the time when the trimming operation is to be performed, there is in such shoes no definite crease between the sole and the upper with which the crease guide of th machine may effectively co-operate in guiding the shoe.

In view of the foregoing, one object of the present invention is to provide a machine which will be adapted to operate progressivealong the bottom margins of shoes not only of the type wherein a welt or other previously trimmed bottom member is provided for attachment to the tread sole but also of the type wherein no welt or equivalent shoe 1930. Serial No. 44737 01.

bottom member is provided, and wherein the tread sole is secured directly to the upper as, for example, in McKay-sewed shoes, turn shoes and shoes in which adhesive is employed as the sole attaching means. I

To the accomplishment ofthis object, and in accordance with the present invention, the illustrated machine is provided, not only with an edge gage for guiding a shoe by engagement with the edge of a welt or other shoe bottom member, but also with an upper gage for guiding a shoe by engagementwith the shoe upper, thus adapting the machine for use in operating upon shoes having no welt edge or other shoe bottom edge capable of being engaged by an edge gage. To this end, a feature of the invention consists in the provision, in a machine having means for operating upon the sole of a shoe as the shoe is fed to advance its sole margin progressively past said means, of an edge gage movable into and out of position to guide the shoe by engagement with the edge of a shoe bottom member while the shoe is being fed and operated upon, and an upper gage movable into and out of position to guide a shoe by engagement with the shoe upper as the shoe is being fed and operated upon, said gages being so connected together and so arranged relatively to each other that when either of the gages is operatively positioned the other gage will be inoperatively positioned. In the illustrated machine the operating means comprises a rounding knife and a channeling knife'and the work is supported and fed by the cooperation of means comprising a feed plate adapted to engage the exposed face of a welt or other projecting shoe bottom margin and a reciprocatory work support arranged to engage the tread face of the shoe bottom.

The illustrated edge gage comprises an arm having an end face for engaging the edge of the previously trimmed welt of a shoe, while the illustrated upper gage comprises an arm carrying a roll for engaging the upper of a shoe in a location close to the shoe bottom. The means herein shown for connecting the gages comprises a rocker stud to the opposite ends of which the gage arms are secured, the rocker stud being journaled in the feed plate and the gage arms extending radially from the rocker stud and being separated by a radial angle such that when either gage is positioned for operation upon a shoe the other gage will be inoperatively positioned. The illustrated edge gage is located between the feed plate and the rounding knife and is provided with an opening or slot arranged to permit the rounding knife to move through the edge gage into engagement with a cutting block in the rear face of the feed plate. As illustrated, also, manually releasable means is provided for locking the rocker stud in two positions in one of which the edge gage is operatively positioned and in the other of which the upper gage is operatively positioned.

The invention will be explained with reference to the accompanying drawing in which Fig. 1 is a View, in front elevation, of so much of a rounding and channeling machine as is necessary to illustrate the application of the present invention thereto, the machine being shown in operation upon the sole of a welt shoe;

Fig. 2 is a view, partially in side elevation and partially in section, of the portion of the machine shown in Fig. 1, this view also showing the machine in operation upon a welt shoe;

Fig. 3 is a view similar to Fig. 2 but showing the machine in operation upon a McKaysewed shoe; and

Fig. .l is a detailed perspective view of the edge gage used for guiding a Welt shoe.

In the drawing, the invention is shown as embodied in a rounding and channeling machine of the general type disclosed in Letters Patent No. 600,883, hereinbefore referred to. The illustrated machine is provided with a fourmotion feed plate 10 arranged to engage the upper surface of the welt, in a welt shoe (or the corresponding portion of the projecting sole margin of a shoe in which no welt is employed such, for example, as a McKaysewed shoe or a turn shoe) a sole support in the form of an anti-friction roll 12 which is movable back and forth to co-perate with the feed plate in feeding the work; afixed work support or crease guide 14 shaped to enter the usual crease between the welt or sole margin and the upper of a shoe; a vibratory rounding knife 16 which is movable toward the feed plate to trim the outsole of the shoe; and a channel knife 18 which is movable with the sole support. The above-described parts are substantially the same in construction and have substantially the same mode of operation as corresponding parts disclosed in said patent and, accordingly, no further description of these parts will be given herein.

To adapt the present machine for use in operating both upon welt shoes and upon McKay-sewed shoes (or other shoes in which the tread sole is directly secured to the upper) for the purpose of rounding or rounding and channeling soles which have been applied to the shoes in the process of repairing them, the machine, in accordance with the present invention, is provided with an edge gage 20 which is movable into position for use when the machine is operating upon welt shoes, and an upper gage 22 which is movable into posi tion for use when the machine is operating upon McKay-sewed shoes or other shoes in which no welt or equivalent shoe bottom element is employed. As herein shown, the welt edge gage 20 is located at the rear of the feed plate 10 while the upper gage 22 is located in front of the feed plate and the gages 20 and 22 are secured respectively to the rear and front end portions of a rocker stud 2% which is mounted to turn in a suitable bearing formed in the upper portion of the feed plate.

The illustrated welt edge gage 20 comprises a thin plate the upper portion of which is integrally connected with the rear of the rocker stud 24 in. such a way that the plate extends radially from the stud at right angles to the axis of the latter. At its lower or outer end the plate 20 is provided with an edge face 28 (Fig. 4) which is adapted to engage the trimmed edge of the welt of a shoe which is being repaired. The plate 20 is further provided near its outer end with an opening or slot 30 through which the rounding knife is adapted to vibrate.

The illustrated upper gage 22 consists of an anti-friction roll which is mounted to turn idly on the outer end of an arm 34 the opposite end of which is rigidly secured to the front end of the rocker stud 2% by means of a screw 35. The front end of the rocker stud 24.- is flattened, as indicated at 36 in Fig. l, to prevent radial displacement of the arm 34 thereon. As shown, the periphery of the gage roll 22 is transversely concave to conform approximately to the curvature of the upper of a shoe in the vicinity of the crease between the upper and the sole. The arm 34 is bent, as shown at 38, so as to position the gage roll 22 close to the work support 14 so that the roll may engage the upper as close as practicable to the sole.

The welt gage plate 20 and the upper gage arm 3d are positioned on the rocker stud 2t so that they extend in different radial directions relatively to the stud. As shown, the two gage arms are separated radially by an angle of substantially Thus. when either of the gages is operatively positioned the other gage will necessarily occupy an inoperative out-of-the-way position.

Provision is made for locking the rocker stud 2 1 in twopositions in one of which the welt edge gage 20 is operatively positioned and in the other of which the upper gage 22 is operatively positioned. This locking is effected by engagement of the lower end of a the original welt.

lock bar 40 with one or the other of two notches 42 and 44 formed in the periphery of adisk 46 which is fast on the rocker stud 24. The disk 46 is clamped between the arm 34 of the upper gage and shoulders 48 on the rocker stud by means of the screw 35. As shown, the lock bar 40 is pivotally mounted between two ears 52 formed on the feed plate 10, the bar 40 being pivoted upon a pin 54 the ends of which extend through the ears 52. The lock bar 40 is yieldingly held in looking position by means of a spring 56 one end of which is seated in a socket in the feed plate while the other end of the spring bears against the up per end of the lock bar. As shown at 58, the upper end of the lock bar is enlarged to adapt it to be conveniently depressed by the operator against the action of the spring'to release the lock bar from looking engagement with the disk.

To adapt the machine for operating upon welt shoes the welt edge gage is positioned, as shown in Figs. 1 and 2, with its lower edge face located behind the feed plate in position to engage the trimmed edge of a welt, such as the welt TV of the shoe S. When thus positioned the slot in the edge gage plate is located in the path of vibratory movement of the rounding knife 16, thus permitting the knife, after cutting through the outsole O of the shoe S, to continue its forward stroke until it engages a cutting block 60 inserted in the rear face of the feed plate. The reason for permitting the rounding knife to move into contact with the cutting block 60 on the feed plate will be made apparent later in describing the operation of the machine in con nection with McKay-sewed shoes. When the gages are adjusted as shown in Figs. 1 and 2, the machine is adapted to trim an outsole which has been applied to a welt shoe in the process of repairing the shoe so that the trimmed sole edge will bear a desired definite relation to the previously trimmed edge of As shown, the newly applied outsole is trimmed slightly wider than the welt to allow sufficient surplus of outsole margin for subsequent finishing operations. To adapt the machine for operating upon McKay-sewed shoes, turn shoes, or shoes 1m ing cemented soles, it is only necessary to unlock the rocker stud 24 by depressing the up per end 58 of the lock bar todisengage the lock bar from the notch 44 in the disk 46 and to turn the stud 24 so as to reverse the position of the gages, thus bringing the upper gage 22 into operative position and at the same time throwing out of operative position the welt edge gage 20. hen the upper gage 22 has reached operating position, the spring 56 will cause the lock bar 40 automatically to engage the notch 42 in the disk 46 thereby locking both "ages in the positions shown in Fig. 3. The upper gage 22 will then be located to guide a shoe by engagement with the both gages in the positions last specified.

ping action the knife cutting against the cutting block 60 in the feed plate.

' hen the upper gage 22 is inoperative position the machine may readily be adapted for operation upon welt work merely by manually releasing the lock bar 40 and readjusting the gages to move the edge gage 20 into operative position, thereby inoperatively positioning the upper gage and moving the notch 44 into position to be engaged by the lock bar 40 for the purpose of locking The fixed crease guide or sole support 14 has no positive guiding function, when the machine is operating upon either welt, turn, or McKay-sewed shoes, other than indicating to the operator whether the shoe is being held. in proper relation to the operating instru mentalities of the machine, the actual guiding of the work being elfected'by the edge gage 20, in the case of welt shoes, or bythe upper gage 22, inthe case of turn or McKay sewed shoes. The sole support 14, however, does cooperate with the work support 12 to support the work in position to be operated upon.
